(11-23) 13:08 PST WATSONVILLE -- A seventh abandoned puppy has been found at an agricultural recycling center south of Watsonville, officials said today.

Authorities believe the Australian sheepdog mix puppy, which they named Felix, came from the same litter as the six other 2 1/2-month old puppies left at the recycling center on Live Oak Road in an unincorporated part of Monterey County last week.

Felix the puppy is smaller than his brothers and sisters and was clean when he was discovered, which SPCA officers believe means he was dumped recently, after his siblings.

"It's been very cold and rainy, and when we rescued the other puppies, they were quite dirty," said Beth Brookhouser, director of community outreach for SPCA in Monterey County. Felix, however, "was very, very clean. He was flea-infested like the rest of them and had some foxtails, but if you rubbed his coat, he had no dirt on him."

Two humane officers spotted Felix's brothers and sisters at the recycling center Nov. 16. Two were playing on the side of the road and the other four were found under a tarp, scared, wet and covered with fleas.

Humane officers think that whoever abandoned the puppies drove to the fence line and threw the puppies over. The SPCA is offering a $500 reward for information leading to the conviction of the puppy perpetrator, who could face could face up to a year in jail and a $20,000 fine.

The original six puppies are "blossoming" under SPCA's care, and the list of potential adopters has grown to more than 100 names, the society said.

All the puppies were reunited for playtime Tuesday, Brookhouser said. A video of the moment shows the puppies romping and welcoming Felix back into the fold.

"Everyone was wagging their tails," she said. "They're happy to see each other."
